I started doing raids recently, and there are lots of occasion where I need to keep track of the other tanks debuff such as in VoA Frost boss. Is there any recommended add on to only show raid specific debuffs that tanks need to keep track (or that can be customised to my need)?
I tried using X-perl but it just shows all debuff (or I can choose to only show dispellable debuff)
VuhDoo with a special group created for tanks would do the trick. It pretty much shows all important debuffs by default and you can only show tanks, not full groups.
And DBM does spam important stuff in chat and on screen. Also MPR works very well and can whisper raid/party members and report tons of stuff to you.
DBM is the thing for you and you can't raid without it. You can edit specifically which boss abilities you want it to warn you about, the location of the warning, color, sound, bla bla.
